The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of t

In 2011, by 1.3 mm wavelength VLBI radio wave observations of the SgrA*, Fish, V. L. et al showed that the emissions tightly related to the formation of a black hole shadow have a remarkably large time-varying feature within a region of less than 50
